Your day in Great Falls
What could you race?
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Great Falls could look like.
The course behind your race
A new full distance on rolling ground.
With no published routes, plan by effort and fuelling. The athlete who holds a full-distance ceiling on the rolling bike keeps a marathon to run.
First half
Cap the opening.
Hold your power ceiling and set your fuelling rhythm.
Cap opening power. Fuel early.
Second half
Protect the run.
Let speed change with the wind and keep power steady.
Hold effort steady. Finish nutrition before T2.
First half
Open easy.
Run the first half slower than you feel you can.
Take every aid station. Keep the opening easy.
Finish
Race what you saved.
Progress only once form has held.
Check posture. Choose the last move late.
